DP and I go to a particular restaurant once a week or so and have been for a while. Everyone there knows us, makes us feel very welcome, always willing to change a dish for fussy DP etc.. But there's this one waitress, who is so flirty with DP it's pissing me off and bordering on embarrassing. DP is completely blind to it (so he says) and I'm not worried about him reciprocating but sometimes I feel it's a bit disrespectful to me. The last time we went there, she went into the kitchen to get 2 new members of staff out to look at him with a 'that's who I've been telling you about' gesture. AIBU to not want to go there anymore or am I being over sensitive?
